关于手动添加CTreeCtrl 的消息处理问题,急！！！~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[wangshengdao]

1。我在MainrFrame::OnCreate里
if (!m_wndTree.Create(WS_CHILD¦WS_VISIBLE¦
TVS_HASLINES¦TVS_HASBUTTONS¦TVS_LINESATROOT,
CRect(0, 0, 0, 0), &m_TabCtrl, IDC_TREE))
{
TRACE0("Failed to create instant bar child\n");
return -1;
}
2。.cpp里手动添加
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
ON_NOTIFY(NM_DBLCLK,IDC_TREE,OnDblclkTree)
END_MESSAGE_MAP()

3。.h里手动添加
afx_msg void OnDblclkTree(NMHDR* pNMHDR, LRESULT* pResult);
4。.cpp里手动添加
void CMainFrame::OnDblclkTree(NMHDR* pNMHDR, LRESULT* pResult)
{

// TODO: Add your control notification handler code here
*pResult = 0;
}
问题：我在双击树控件是OnDbclkTree却没有被调用，为什么？怎么改才好？不胜感激！！
